Application filed May 2,

To all whom it may concern:

Be it known that I, HARRY E. STALTER, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in a Out-Ofi' Slide Attachment, of which the following is a specification. I I 1 My invention has reference to a cut-off slide attachment, such as are. used with turret lathes, and has for its purpose to facilitate the operation of producing washers .from a piece of tubing. In some cases the washers which are cut from thev tubing possess so little thickness that it is a diffi} cult matter to pick them up. As they are severed from the end of the tube they fall intothe oil and filth'with which the machine is surrounded, and after the machine is .Fig. 2 is a transverse section, on the line 2 -2 of Fig. 1 I

Fig. 3 is an enlarged view of the inven tion, detached.

1 represents a portionof'the table of a turrent lathe, and 2 a head mounted thereon, and provided with a cutter-block 3, carrying a knife-4. '5 indicates the end of a.

lathe, in which is held a tubular member 6, so as to be fed graduallytoward the knife 4. In practice several of the knives 4 would be employed, each one making a partial'cut on the tube. The knife 4' is assumed to be the one which will perform thefinal operation,

7 by means of which a ring, or washer will'be completely severed-from the tube. 7

Fixed to'the head 2 is a plate 7 by means of a bolt 8 secured in said head, and passing through an opening in one end of the plate. The opposite end of said plate is-perforated to receive a rod 9, which can be held in ad-.

. tion on the machine. 5

j'usted positions therein, vertically,

means of a thumb-screw 10. The lower end -of'the rod 9 is provided with anopening to receive the threaded end of a'- rod 11, of less 1 diameter than the rod 9,- and held in place 1 by nutsl2 and 13 on opposite sides of the rod 9'. Therod 11 passes through an open- Iknife.

The end of the'rod llis sufficiently close I to the knife 4: to catch thewasher as it is downwardly along the rod by force of gravity, or'by pressure from the. next succeedingwasher as it] is severed from thetube;

A series of the washers is therebystrung upon the rod 11, and can be easilyslipped therefrom by the hand of the operator wh Y it is desired-to remove same,

" It is evide'nt that the rod 11 can be 7 ing 14.- in the head 3,'and'has its free end in q a proximity to the "knife-4C. Said rod .is also preferably inclined upwardly toward said severed bvsuch'knife, the washer moving brought into proper position, vertically,-by

adjustment ofthe rod 9, and longitudinally by means of the nuts 12 and'13, If. at any time it is desired to use the machine without" the attachment the rod 9 can be disconnected from the plate 7 leaving such plate inposi- If desired, the opening rodll, longitudinally1 7 What I claim ters' Patent, is: V 1. A device of the classdescribed, comin the plate .7' through which the bolt 8 passes, indicated in broken lines at 15 can be of elongated form,

soas to permit" a quick adjustment of the} and desire to secure by Let- I i I prising a plate adapted, for attahment to the head of a turret lathe; a rodsupported .vertically in said plate; and a rod of smaller diameterthan said first-named rod, supported thereby so as to have itsufree end in proximity to the cutting device of said'head.

' 2A devicev of'the class described, come prising horizontal supporting member, 'v i I adapted for attachmentto the.; t ff Slide. I 1

of'a turret Ilathe; a vertical member connected with said supportlng member; and a rod supported by said vertical'member in approximateparallel relationwith saidhori zontal member, and so as to be capable of adjustment with relation thereto.

r 3. A device of the class described, comprising a plate adapted to be secured in horizontal position on the cut-0E slide mechanism of a turret lathe; a vertical rod secured in said plate, so as to 'be capable of 5 rotation therein; means for adjustment of said rod, vertically; a rod of smaller diam eter than said first-named rod, supported in the lower end thereof, and inclined up- Wardly into juxtaposition with the cutting devices of said slide; and means for adjust- 10 merit of saidlest nametl' i'od, E longitudinally.

In testimony whereof 1 Mix my signature.
